Abstract (en)

Two heat exchangers, such as a condenser for cooling refrigerant circulating in an air-conditioner and a radiator for cooling coolant in an internal combustion engine, are combined into a single unit (100). Both heat exchangers are overlapped in an airflow direction of cooling air. Each heat exchanger has a similar structure composed of a core (110, 120) having plural tubes (111, 121) and fins (112, 122) and a pair of header tanks (113, 114, 123, 124) connected to both ends of the tubes. Two heat exchanges are combined by a side plate (130) disposed on the upper side thereof. The openings of both header tanks are closed with separately formed tank caps (113d, 123d) and are connected to the side plate (130) through the tank caps. Direct heat transfer from one header tank to the other header tank, e.g., from the radiator tank (123, 124) to the condenser tank (113, 114), is prevented because both header tanks are connected to the side plate (130) through separate tank caps, thus achieving a high heat radiation capacity in the compound heat exchanger. <IMAGE>
